MICRO2440 7" lcd ARM9 board S3C2440 256M nand SKU217


micro2440 and mini2440 The main differences:
1. With the core board + floor forms the core board with six laminates designed, more stable operation, convenient unit of user development;
2. Button and camera interface to set aside in the LCD liquid crystal screen, the user-friendly design uses;
3. An increase of two serial interface DB9 interface, user-friendly applications in three serial occasions; more 3 TTL-level com extraoral cited;
4. Backplane to add built-in microphone, get rid of the audio input port;
5.JTAG interface in the core board, even if detached from the floor also will be carried out the system debugging;
6. Software resources is basically the same! If you are using mini2440 carried out prior to product development, migration procedures to micro2440 development board is very convenient!
Master 7.4 USB port (USB Host), more than mini2440 more 3 and more easily extended to other modules
micro2440 core board with six laminates design and use of a long route in order to meet signal integrity requirements. The development and easy maintenance from the debugging point of view, we have the main chips are placed on the top; for the convenience of plug and leads to more CPU signal pin, the core board with 2.0mm Pitch "U"-type arrangement of pins, so we are also often It is referred to as "U"-type core board-U2440.
micro2440 is actually a minimal system board, which contains the basic power supply circuit (5V supply), reset circuit, the standard JTAG debug port, users debug light, as well as the core of the CPU and memory modules, etc.. FLASH memory cell which contains NAND FLASH and NOR FLASH two types, through the jumper J1 can choose to boot from NAND or NOR. General NOR FLASH is not placed inside the frequently changing BIOS (we use the supervivi), NAND FLASH which is Shaoxie a complete system program (bootloader, kernel, file system, etc.).
Micro2440 floor resource characteristics

* 1 CMOS camera interface 20Pin 2.0mm pitch pin can be directly connected to the company's CAM130 camera module.
* 10-pin 2.0mm pitch JTAG Interface
* 1 power supply input, +5 V power supply
7-inch screen with a base hit with random packages
1. Micro2440 core plate and a floor (in September the new 256M NAND memory)
3. DB9 serial cable with a straight
6. Easy JTAG small board (can be carried out with H-JTAG debug single-step simulation) a
9. A beautifully packaged box (for easy transportation and maintenance, you should keep)
